Hey guys. I'm working on a Joel Robinson costume from MST3K and I have all of my plans ready, but one little caveat: The helmet. I have a yellow construction helmet, but it's the little Gizmonics G logo on the front which I need to replicate. Any idea on how I could make one or apply it? Here's a picture of the logo:

You could print it out on fairly thick card or a large sticker, cut out the centre bit, stick on the outer bit, mask off the rest of the helmet and spray paint it or just get a brush with some paint and paint over the template
